If you really believe that, then you have no idea how the economy works.
1: It COSTS money to round up those illegal immigrants. So your taxes will go up in some ways. (data point: http://www.newsweek.com/how-mu...)
2: Those illegal immigrants most of who are working and actually contributing to society. (in the form of taxes and general purchasing) they may be illegal but they are give far more than they take). - (data point: http://www.politifact.com/pund...)
3: The places that employed them were doing so not out of the goodness of their heart, but cheap labour, which means they will now have to pay standard wages.. which means, costs where they were working will go up, which WILL be passed on to you the consumer. (ie: Post Tax money from you)
4: A tourist, in general, is a net positive gain for a country, ie: someone that spends money, but consumes so little in services that they are net positive for a country (its a reason why lots of countries with little industry go to tourism, as its a vehicle for revenue and requires relatively little investment.
So 3000 per year for one family may not sound like a lot, but lets assume most spend half that, and in 2015 there were 38 Million visitors to the US.. (so lets quarter that for families (figuring a typical house of 4) or about 9.5 million families visit. Now lets assume about half of them are business travelers (and many companies are looking to stop sending bodies to the US and go virtual) so we have 4.75 tourist families.. now lets assume half them are skipping the US (which most I know are.. I know personally the CEOs the top travel agencies in the Europe (western) and Asia (east) and they are have noticed that since Trump's election, over 20% of the reservations they had for families that were coming to the US have cancelled or changed their plans to other places). We have no stats on personally booked travel and other travel agencies, but if their numbers are similar, then a 50% reduction is not far off, which puts us at about 2.35 Million familes that won't visit. Which means a reduction of 3,562,500,000 dollars (3.5 Trillion dollars) annually gone from businesses (some of which depend on tourists), which means those businesses will reduce staff (ie: more people looking for work).
Add that to the other things going on...
Well, its not good.
